This is a major changes release. API is now more stable, filters classes benefits from a better abstraction, AHAH helpers, and UI have been revamped. A lot of bugfixes have been made during the process.
It also add a new feature, the "Quick search" toolbar. This is not a direct search toolbar. It allow user to do a common query like he would do using any other search engine, and an Ajax action will parse it and create one or more matching filters.
Contextes can now define if the form should, or should not enable this feature.
Site administrators can also choose if they want to use our own Apache Solr Service, or keep using the Apache SolR Integration module default one. For now, this does not have any impact, but more features will keep coming and will benefit from our own implementation (which extends the legacy Apache SolR Integration module one by the way).
JavaScript have been rewrote, and should be more efficient and less buggy.
